GAS-STOVE.

SPECIFICATION forming part of Letters Patent l \To. 646,684, dated April3, 1900.

Application filed August 6, 1893' Serial No. 687,887- (Ilo model.)

- To ctZZ 1072 0721, it may concern:

Be it known that I, JOHN ARTHUR DAILEY, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan,

hygienic principles in which thelgas-flame is burned in close proximityto awater-tank, in which the water-vapor is thoroughly dried and mingledwith a large body of air before being allowed to pass into the open airof the room, and in which the products of combustion escape from theroom.

My invention further consists in combination of parts by whichcompactness, efliciency,

- and simplicity are secured.

In the drawings, Figure 1 is a perspective showing the interior parts ofthe stove. Fig.

' 2 is a horizontal section through the stove at the bottom of theair-flues. Fig. 3 is a perspective showing a back view of the watertank.Fig. 4 is a Vertical section showing the air-chamber, water-tank, andburner.

A indicates the stove-base, supported from the floor on legs a andhaving what may be termed the rear half of it open for the free entranceof air through the holeb into a chamber 29, that occupies the rear halfof the space inclosed by the casing (which is indicated by the dottedlines) and below the first diaphragm c. The front half of the spaceinclosedwithin the same casing above the base A and below the plane ofthe diaphragm c is the first combustion-chamber, and in it are located awater-tank d and the gas-burner e. The water-tank is made as a vesselthat is entirely closed on those sides which are next adjacent to thefire.

The water-tank may be made in any suit able shape. As shown in thedrawings, it is made in the shape of the half of a frustum of a cone,with the small end downward, the large end upward and closed, and. theflat wall at the rear of the frustum extended to the stovewalls by thewings cl ri and across the walls of thewater-tank, near the top, is anopening thatballows vapor to escape into the chamber The first diaphragm0 covers the chamber 1) and the water-tank having one or more openingsto be connected with tubes for the passage of air, leaving thehalf-annular opening at the front between the edges of the diaphragm andthe outer walls of the stove. Through this half-annular opening theprod= nets .of combustion pass upward from the burner e to the seconddiaphragm c.

The second diaphragm 0 lies across the stove from wall to wall,with oneor more openings to correspond with openings in the first diaphragm forthe passage of air through the tubes before mentioned, and leaves anopening at the rear between its rear edge f and the stove-walls, throughwhich the products of combustion may pass upward around the diaphragm c.

A third diaphragm 0 similar in shape to the second diaphragm 0, havingone or more openings to correspond with the first and second diaphragms,lies spaced from the second diaphragm above it, closing the upward passage at the rear, but opening it at the front between the edge f and thewalls of the stove, so that the products of combustion may pass upwardbeyond this diaphragm on the way to the pipe 1).

Above the exit-pipe p is a fourth diaphragm 0 with openings tocorrespond with the first, second, and third diaphragms, which entirelycloses in the upper side of the last chamber b except the air-fines,which pass from the lowerdiaphragm to this one. Above the last diaphragmc is the ornamental stove cover or dome, provided with perforations topermit the escape of rising air which comes through the lines 72.

Flues, one or several in number,rise through the several diaphragmsleading from the first or air chamber 1) to the chamber immediatelybeneath the dome D. While only three diaphragrns are shown intermediatethe'fire and the exit-pipe any number of such diaphragms, may be usedsufficient to retain the heated gases in the stove until they haveimparted all or nearly all their heat to the flues hand heated the airrising through the flues h, and while IOC only two flues h are shown inthe drawings this number may be decreased to one or inincreasedindefinitely, so as to produce a large heating-surface to be acted uponby the heated gases.

g indicates the inlet-pipe for gas, and 10 indicates a filling-pipe forthe water-tank 61.

Preferably the water-tank when placed next adjacent to gas-burner shouldbe coated on its front side with asbestos, but can be left withoutanything, and this asbestos should preferably be of the fibrous kind,such thatit may beeomeincaudescent in the flame and furnish the lightand genial appearance produced by burning gas against fibrous or woolyasbestos. The asbestos thus not only becomes a source of beauty in thestove, but protects the water-tank from becoming too greatly heated,furnishing a large radiatingsurface to receive and radiate the firstimpact of the burning gas.

The entire stove is held together by bolts and rods in the usual way.

In action the heated products of combustion pass from the fire back andforth across the stove between the several diaphragms, and on eachpassage across the stove the heated prod nets of com bustion strikeagainst the airflues which conduct pu re air up through the stove to thetop of it, thus imparting the heat to a circulating current of moist airwhich is circulated in the room.

What I claim is 1. In a gas-stove the combination of an airchamber, acombustion-chamber, a burner located in said combustion-chamber, aWatertank adjacent to said burner and opening into said air-chamber,flues leading from said air-chamber, and a passage-way leading from saidcombustion-chamber around said flues whereby a draft is induced throughsaid fines, and the vapor, and air in said fines are thoroughly driedand mingled, substantially as shown and described.

2. In a gasstove, the combination of the casing, a combustion-chambercommunicating with the interior of said casing, an airchamber, awater-tank adjacent to said combustion-ehamber and opening into saidairchamber, fines leading from said air-chamber, and a series ofperforated diaphragms in said casing surrounding said i'lues,substantially as shown and described.

3. In a gas-stove, the combination of a casing, the lower part of saidcasing being divided into a combustion, and an air-chamber, a water-tankadjacent to said combustionchamber and opening into said air chamber,flues leading from said air-chamber through said casing, and a series ofperforated diaphragms in said casing, above said chambers surroundingsaid flues, substantially as and for the purpose described.

In testimony whereof I sign this specification in the presence of twoWitnesses.
